Methods, apparatus, and computer readable media applicable to balancing robots. Some implementations are directed to maintaining a given end effector pose (relative to a world frame) of an end effector of a balancing robot when there is a disturbance to a balancing base of the balancing robot. Some implementations are additionally or alternatively directed to transitioning a balancing robot from a fallen configuration to a balanced configuration. Some implementations are additionally or alternatively directed to mitigating the risk that a balancing robot will fall when interacting with actuable environmental objects (e.g., doors) and/or to lessen the disturbance to a balancing base when interacting with actuable environmental objects.

Artificial ankle-foot system with spring, variable-damping, and series-elastic actuator components

An artificial foot and ankle joint consists of a curved leaf spring foot member having a heel extremity and a toe extremity, and a flexible elastic ankle member that connects the foot member for rotation at the ankle joint. An actuator motor applies torque to the ankle joint to orient the foot when it is not in contact with the support surface and to store energy in a catapult spring that is released along with the energy stored in the leaf spring to propel the wearer forward. A ribbon clutch prevents the foot member from rotating in one direction beyond a predetermined limit position. A controllable damper is employed to lock the ankle joint or to absorb mechanical energy as needed. The controller and sensing mechanisms control both the actuator motor and the controllable damper at different times during the walking cycle for level walking, stair ascent, and stair descent.
